FICM-V & Battery Voltage Question
#16
#17
Seems like some pretty low numbers to me. Pulling two good 850cca batteries down even close to that far seems like quite a work out for them, and the alternator. Someone posted lately they leave the auto headlights, heater fan, seat warmers etc. Off until the glow plugs go off and the alternator comes on (batt volts come up). seems like a good idea.

Here is what you are looking at to get the FICM out.
1. Remove the air filter box. There is a good video in the tech folder for doing this.
2. Draining coolant is optional, but in my opinion is well worth the time. Open the radiator petcock and drain about 2 gallons of coolant into a CLEAN bucket. Remove the two small hoses from top of the degas bottle, and loosen the large hose clamp on the bottom of the bottle. Then remove the two screws that hold the bottle to the cowling and remove it.
3. Here is what you'll see at that point. Stuff a rag down the turbo intake. You don't want anything dropping down that throat!
4. Remove the bracket that clamps the front of the FICM down and attaches to the intake duct. Then remove the 2 screws that hold down the rear of the FICM. This is an '06, the FICM bolts are a little different on earlier years, or so I have been told.
5. Reach under the loose FICM and disconnect the 3 harness connectors. This is the hard part, especially the first time. You want to squeeze the connector clips while you wiggle them out. Here is a shot of the connectors.
Here is a closeup of the connector. Squeeze where the white dot is placed. The same tab is on the opposite side, so squeeze them both together and wiggle the connector. It is in an oil tight socket, so it takes some wiggling to pull out.
Here is a closeup of the interlocking tab on the socket. It should help to have seen how it all works. You'll be working blind under the FICM.
6. Reinstall in the reverse. Make sure the connectors click solidly in place.
Refill with the saved coolant. It won't all go back in until you've driven the truck and worked all the bubbles out of the system. So keep it clean in a covered bucket. I can do this in less than an hour, after having done it a few times.

Looks like "ED" is going to be getting two FICMs in short order, hoping to get mine out of the truck tonight and get it sent to him tomorrow. Stupid dealership..

I've always been a supporter of Interstate brand. And I still am, but to be honest I had one fail at only 26 months. So they are not perfect, but I guess nothing is. I learned that if you have one fail on a weekend, away from home, and you need one fast, the warranty is worthless. I bought them again, but it was a disappointment in the company.

It's amazing how much information there is to know about these engines and all of their idiosyncrasies. Time to update the FAQ page some more.
Those were some truly excellent pictures, Bill. I may ask you about swiping them for our site, in fact. Amazingly well done. The 6.0 crowd is truly top shelf.

Got the FICM back yesterday from "ed" & although i only took it for a short drive yesterday (i will be driving it to work today) it seemed perfect
The voltage never went under 48 (even when initally started) stayed right on 48.5 most of the time & even had a peek on 49 so i assume all will be fine now for our trip.
The dealer gave my batteries a certificate of perfect health & while truck was down i had the alternator bench tested at 2 places because of the "diode" fault the dealer seen in 1 of its many tests & it shows No problems either.
So it looks as if we are good to take off this weekend with the 5th wheel, this will be the first trip pullin camper with this truck (just got the diesel a couple months ago, i had a V10 gas'r) & iam super excited
Thanks again to "ED" for your kindness & quick/good work

Thanks very much for the business, sure, but thanks even more for the support!
Now to find the time to incorporate Bill's pics on the site...

It's always a good feeling to finish working on a module knowing that someone was helped.
Thanks very much for the business, sure, but thanks even more for the support!
